Security is handled by the Facilities Management Division of county government.

Clarke said the deputy was able to get through six checkpoints with no credentials with a gun tucked in her waistband, even though she set off of the walk-through magnetometer.

Each time it went off, the security officer used a handheld wand to locate metal, but stopped after the deputy showed her belt buckle as the source, Clarke said.

The sheriff responded by assigning deputies to the main the checkpoints on overtime earlier this week. He blasted the Facilities Management Department for complacency, and pointed out that department is overseen by County Executive Chris Abele.

"Of course I care, and of course, I'm concerned about any issue with security, which is why we had asked them for a meeting weeks ago," Abele said.

Abele said the sheriff never responded to his call for a security meeting and said in spite of the fact that the deputies have been assigned there since the start of week, Abele didn't learn about the security concern until reading the sheriff's news release on Wednesday afternoon.

"Nobody is anti-public security. Everybody cares about it. Your viewers get, we all care about security. But we address issues like this and everything else when we just pick up the phone, call the other professionals we work with and act like professionals and look for solutions not fights," Abele said.

Abele wants his office to review surveillance tapes of the incident and said he is waiting for the sheriff to offer details on exactly when the undercover operation played out.

WISN 12 News tried to talk with the sheriff Wednesday, but was told he was hosting a talk radio program this afternoon, and declined repeated requests for an interview.

The sheriff's news release said he will request additional funding to pay the overtime costs of the deputies now working the courthouse entrances.

Clarke said he did the "integrity check" following the shooting at a courthouse in Wilmington, Del., last month.
